Thread: Question about Dmax/allison

I test drove a 2003 cheverolet 2500 2wd with the 6.6 LB7 with auto. What trans did it have? I thought all duramax were paired to the allison trans but it just had a duramax badge on the door nothing else.

Sorry for a dumb post I'm too lazy to subscribe to any diesel forums and i couldn't find much with a quick google search.
